At what ph is enzyme A working at its maximum rate

1 answer:

5 0

Enzymes are also known as Biological catalysts. An enzyme working at its maximum possible rate, where the substrate concentration is in excess is V max.

The reaction is slow because the molecules are moving slowly and they will not often collide with the active site of an enzyme, so the binding of an enzyme and substrate is rare.

Cats and dogs are both mammals because they have hair, are warm-blooded, and nourish their young with milk. Dogs and cats are distinct species, incapable of producing offspring together because of the many differences in their genome.

Plastids that are surrounded by more than two membranes are evidence of

dimaraw [331]

Answer:

d. secondary endosymbiosis.

Explanation:

When a living cell acquires another organism that eventually becomes a part of this cell, this process is known as primary endosymbiosis.
When an organism that has already undergone primary endosymbiosis engulfs another eukaryotic organism then this process is known as secondary endosymbiosis.
Secondary endosymbiosis has been known to occur in plastids because of which they are surrounded by two membranes. This bilayer is present because one of the layers is the original outer membrane of the organism and the other membrane is that of the organism that has been engulfed.

What layer of the blood vessel wall is composed of areolar connective tissue containing elastic and collagen fibers

Gekata [30.6K]

Hey There! Hope you are having a GREAT day!

Your question was.... "What layer of the blood vessel wall is composed of areolar connective tissue containing elastic and collagen fibers"

Your answer is the Tunica intima, Because, The blood vessel's tough outer layer is made up of connective tissue, which permits it to withstand stresses occurring on the vessel wall. It also contains strong collagen fibers that help bind the blood vessel to surrounding tissues, providing stability to the vessel.

I really hope this helps! :)

In humans, blue eyes are inherited as a recessive autosomal trait and color blindness is an X-linked recessive trait. A woman wi

sergiy2304 [10]

Answer:

A) One-half of their daughters will have normal color vision and brown eyes; 1/2 of their daughters will have normal color vision and blue eyes.

Explanation:

The genotypes and phenotypes are:

BB or Bb= brown eyes
bb= blue eyes
XᴰXᴰ, XᴰXᵈ (women) or XᴰY (men)= normal vision
XᵈXᵈ (women) or XᵈY (men) = color blind

A woman has blue eyes (bb) and normal color vision (she has an Xᴰ chromosome) but her father was color-blind, so the other X chromosome she has carries the recessive d allele. She has the genotype bb XᴰXᵈ.

The man has normal color vision (he is XᴰY) and has brown eyes, but his mother had blue eyes so he must have inherited a b allele from her and is therefore heterozygous Bb. His genotype is BbXᴰY.

The blue/brown eyes gene is autosomal and independent from the sex-linked color blindness gene.

The woman can produce the gametes b Xᴰ and b Xᵈ.

The man can produce the gametes B Xᴰ, b Xᴰ, B Y and bY.

The female daughters can have the following genotypes and phenotypes:

Bb XᴰXᴰ brown eyes, normal color vision
Bb XᴰXᵈ brown eyes, normal color vision
bb Xᴰ Xᴰ blue eyes, normal color vision
bb Xᴰ Xᵈ blue eyes, normal color vision
